. Fig. 5 a section onthe line 55 in Fig. l.

1 marks the sky light box, 2 side plates resting on the ends of the side walls, a plate 3 along the upper side anda plate 4 along the lowerside. The plate 3 is secured to the box preferably ofwood and its upper edge has a fold 5 terminating in a gutter 6, the inner edge of the gutter being folded at 7 to form a glass support. A cap piece 7 is arranged over the'top edge of the glass. A re-enforcing and supporting plate 8 issecured on the inner face ofthe wall 3, the upper edge ex tending into the fold 5. This has an inwardly extending flange 9 terminating in a gutter 10. The flange 9 rests on the top of the box 1.

The side plate 4 has an inward fold 11 forming a flange resting on the top of the side box. Truss bars, 12 are formed of sheet metal of prismatic shape of triangular sec- .tion, the top having supporting surfaces 13 between which is formed a trough 14. The sides of the bar 15 are brought together at 16-and have outwardly extending flanges 17 terminating in an upturned bend 18. The bottom edge's'are locked together by a tie plate 19 which has folds 20 extending over the edges 18, the upturned edges forming a gutter which will receive and carry out any condensation that may reach the truss bar. Glass'21 rests on packing strips 22, prefer ably of asbestos which form cushions for the edges of the glass and'also tend to close the joint between the glass and the bar.

A cap 23 extends lengthwise of'the joint formed between the edges of the glass. A bolt 2 has its head '25 secured Within a bridge piece 26 securedin the gutter 14 A nut'25 arranged on the topof the cap secures the cap in placeJ A tr uss rod 27 is arranged within the bar 12." :It extends around a strut 28 at the center and through the side walls 3 and 4 and through longitudinally extending band;

strips 29 alongthe outer faces of the side walls, the ends" of the rods being provided withnuts 30. The strut28 is formed of a triangular plate with side flanges :31 which are secured to the walls 15 by screws 32. i

f The upper edge'of the side plate 4 has a flange t terminating in an inturned hook 4'. A bottom strip 33"extends along the bottom edge of the glass. This 'striphooks over the bottom of the glass and the edgeof the botima es tom of this ,hookstrip has an out-turned I bar 35 similar to the bar 12 is used in connection with the wall, or plate2 and in this bar no truss rod isusedand the cap atthe top is only a half cap 86; Otherwise the'structure is similar to the bar 12 and the cap23.

What 'I claim as new is w 1. Ina sky light, the combination of a truss barcomprisinga sheet: metal structure of prismatic shapeand triangular cross section with a horizontal side at the top; a" truss rod within the bar; and side walls abutting the ends of the bar. r

-.-2. In "a sky light, the combination of a truss bar comprising a sheet metal structure o'fprismatic. shape and triangular cross sectionwith afhorizo-ntal' side at the top; side wallsabutting the ends of the bar; and a truss rod within the bar extending through the side walls. 1

' 3(Inra skyzli'ght, the combination of a truss bar comprising a sheet metal structure of prismatic-shape and triangularcross section with a horizontal side at the top; side walls :abutting the ends of the bar a truss side wallsgand band strips along the outer b end 34 which hooks into the hook, or return faces of the side walls to which the truss rod is secured.

4. In a sky light, the combination of a truss bar comprising a sheet metal structure of prismatic shape and triangular cross section with a horizontal side at the top; a truss rod within the bar; and a strut for the rod secured to the side walls of the bar.

5. In a sky light, the combination of a truss bar comprising a sheet metal structure of prismatic shape and triangular cross section with a horizontal side at the-top, said top having glass supporting faces at each'sid'e and an intervening gutter; and a truss rod arranged Within the bar.

6. In a sky light, the combination of a truss bar comprising a sheet metal structure of prismatic shape formedwith a horizontal side at the top side wallsijoinedat the bottom; flanges extending from the bottom. of the side wallsforminggutters; means for securing the bottoms of the'side walls together; a truss rod arranged Within the bar, said truss rod having its ends secured to the top of the bar and its'i-ntermed-iate, portion adj acentto the bottom of the bar and a strut lower edges and arranged beneath the glass, said side plate having an outwardly extending flange with a hooked edge; and an edge plate extending along the bottom edges of the glass having an inturned portion below the glass with a hooked edge engaging the hooked edge of the side plate.

11. In a sky light, the combination of truss bars; and a side plate having an inwardly turned loop forming a box support abutting the ends of the truss bars.

In testimony whereof I have hereunto set my hand. r
